[0043] Reference Figure 3 and Figure 5The bottom end of the lifting rod 33 is connected to a control assembly 36 for controlling the lifting rod 33 to move up and down. The control assembly 36 includes a rotating rod 361, which is rotatably mounted on the installation box 31. A second servo motor for controlling the rotation of the rotating rod 361 is fixedly mounted on the installation box 31. The second servo motor is arranged at the rear of the installation box 31 and is not shown in the figure. A rotating disk 363 is fixedly mounted on the rotating rod 361. The rotating disk 363 is provided with a first connecting groove 3631. The first connecting groove 3631 includes a circular arc groove section 3632 and a concave groove section 3633 concave toward the center of the rotating disk 363.

A connecting rod 3651 is slidably installed on the rocker frame 365 through the waist-shaped groove 3653, and the connecting rod 3651 can also rotate in the waist-shaped groove 3653. A ring 3652 is installed on the connecting rod 3651, and the ring 3652 is rotatably connected to the bottom end of the lifting rod 33.

[0044] Reference Figure 5 and Figure 7 A pushing assembly 37 for controlling the rotation of the rotating drum 32 is installed on the rotating rod 361, and the pushing assembly 37 includes a rocker rod 371, and the rocker rod 371 is fixedly installed on the rotating rod 361, and the rocker rod 371 is staggered with the turntable 363 on the rotating rod 361. A second connecting groove 372 and a third connecting groove 373 are opened on the side wall of the rotating drum 32, and the second connecting groove 372 and the third connecting groove 373 are cross-arranged on the rotating drum 32. An avoidance opening is opened on the rotating drum 32, and the avoidance opening is opened on the diameter of the rotating drum 32. The projections of the head and tail ends of the second connecting groove 372 and the third connecting groove 373 in the vertical direction are just connected to the avoidance opening opened on the rotating drum 32, and the rocker rod 371 controls the rotation of the rotating drum 32 through the second connecting groove 372 and the third connecting groove 373.

[0045] Reference Figure 3 , Figure 4 and Figure 5 When the equipment is cutting, the profile is pushed into the positioning frame 34 on one side and abutted against the push plate 352 to position the profile to prevent one end of the profile from exceeding the cutting line and causing excessive cutting and waste of materials. When the profile cutting is completed, the second servo motor controls the rotating rod 361 to rotate, and the turntable 363 and the swing rod 371 on the rotating rod 361 rotate at the same time. Figure 4 This is the state before one end of the swing rod 371 enters the second connecting groove 372. Figure 4First, the rocker frame 365 slides in the arc groove section 3632 on the rotating disk 363, and one end of the rocker rod 371 rotates and is ready to enter the second connecting groove 372 on the rotating drum 32. After the rocker rod 371 enters the second connecting groove 372, the rocker rod 371 pushes the rotating drum 32 to rotate through the action of the second connecting groove 372, and the rotation of the rotating drum 32 drives the lifting rod 33 to rotate; when the rocker rod 371 just rotates out of the second connecting groove 372, as shown in FIG. Figure 5 In the state shown, the rotating drum 32 has just rotated 180 degrees, and the positioning frame 34 has just rotated 180 degrees so that the side without cutting waste faces the cutting table 11. At this time, the rocker frame 365 has just completed the arc groove section 3632 and is ready to enter the recessed groove section 3633.

[0046] Reference Figure 3 , Figure 5 and Figure 6 , the rotating rod 361 continues to rotate, the rocker frame 365 enters the concave groove section 3633 on the rotating disk 363, and the rocker rod 371 does not contact the rotating drum 32 and enters an idling state. The concave groove section 363 drives the end of the rocker frame 365 close to the rotating disk 363 to swing upward, and the rocker frame 365 rotates on the supporting rod 364, and the end of the rocker frame 365 connected to the lifting rod 33 swings downward, thereby pulling the lifting rod 33 to slide downward on the rotating drum 32. When the lifting rod 33 slides downward, it drives the positioning frame 34 to move downward. Because the rotating drum 32 cannot move downward, the push rod 353 connected to the rotating drum 32 cannot move downward. When the positioning frame 34 moves downward, the push rod 353 rotates toward the outside of the positioning frame 34 with the position connected to the rotating drum 32 as the center, thereby pushing the push plate 352 to slide in the positioning frame 34 to push the cut waste out of the positioning frame 34, so as to facilitate the next cutting.

[0047] When the rocker frame 365 has just traveled through the concave groove section 3633 and is ready to enter the arc groove section 3632, the positioning frame 34 rises to prepare for the next cutting and positioning. At this time, the other end of the swing rod 371 has just moved to the position of the third connecting groove 373 and is ready to enter the third connecting groove 373. When the next round of cutting is completed, the rotating rod 361 rotates, the rocker frame 365 enters the arc groove section 3632, and the other end of the swing rod 371 rotates into the third connecting groove 373 to control the rotation of the positioning frame 34. When the other end of the swing rod 371 rotates out of the rotating drum 32, the rotating drum 32 just rotates 180 degrees to complete the alternation of the two sides of the positioning frame 34. At this time, the rocker frame 365 has just traveled through the arc groove section 3632 and is ready to enter the concave groove section 3633. The rotating rod 361 continues to rotate, so that the rocker frame 365 enters the concave groove section 3633, and the above-mentioned blanking process is completed. The positioning frame 34 is used to facilitate rapid positioning of the profile, and the cut waste of the profile is placed in the positioning frame 34 during cutting to prevent the blanks from following the cutter out of the cutting table 11, and the blanks are pushed out of the positioning frame 34 by the blanking assembly 35 so that the blanks can accurately fall into the waste frame 12, which is convenient for collecting the blanks and is beneficial to improving the convenience of the cutting equipment for door and window profiles during use.

A second pressing block 425 is fixedly mounted on the output shaft of the second cylinder 424. In this embodiment, the second pressing block 425 is also made of rubber material.

[0050] After the profile is transported to the cutting table 11, the second cylinder 424 starts to push the second pressing block 425 to press the profile against the first support frame 411 to fix the profile in the horizontal direction, and then the first cylinder 415 starts to push the first pressing block 416 to press the profile against the cutting table 11 to fix the profile in the vertical direction. The first pressing block 416 and the second pressing block 425 are both made of rubber material to prevent damage to the profile during fixation, and can protect the profile. When the cut profile is wider or narrower, in order to achieve a good fixing effect, it is necessary to fix it in the middle position in the width direction of the profile, turn the first handle 414 to unlock the first mounting plate 413, and drag the first mounting plate 413 to move on the first support frame 411 to change the downward pressing position of the first pressing block 416 in the vertical direction, so as to facilitate the quick adjustment of the first pressing block 416. When the cut profile is higher or lower, the second handle 423 is rotated to unlock the second mounting plate 422, and the second mounting plate 422 is dragged to move on the cutting table 11 to change the horizontal clamping position of the second pressing block 425, so as to facilitate quick adjustment of the second pressing block 425.
